Rock Krawler JL45AX2NL-392CS 4.5" Adventure-X2 No Limits Long Arm Coilover Suspension Lift Kit

The Rock Krawler JL45AX2NL-392CS is a 4.5-inch Adventure-X2 "No Limits" Long Arm Coilover Suspension System engineered as the ultimate balance between daily driver comfort and hardcore off-road capability. Purpose-built for the 392 V8 platform, this system features 392-specific valving and a heavier-rate coil spring combination in the front coilovers to properly account for the added weight of the 392 cubic inch V8 engine, delivering a balanced and functional lift.

Adventure-X2 Long Arm Architecture:

• Combines a full high-clearance 4-link front suspension with a high-clearance independent 3-link rear suspension
• Service-free Adventure Series joints throughout — no greasing required
• High clearance long arms and 3-link geometry maximize trail performance and articulation
• X2 rear suspension geometry with enhanced rear instant center and rear roll center for adjustable anti-squat
• High-clearance axle mounts provide 4.5 inches of additional ground clearance under the rear axle versus stock
• Rear upper shock relocation brackets preserve full shock and suspension travel

"No Limits" Sway Bar Link System:

• Designed specifically for Rubicon owners to retain use of the factory electronic sway bar disconnect feature
• CNC machined billet aluminum center section with factory-sized hardware
• Made-in-USA heim joints sourced from FK Bearing

Triple-Rate Coilover Suspension:

• All four coils tuned together for on-road comfort that surpasses OEM linear rate springs
• Coils built with proper free-length for maximum off-road articulation and secure seating in the coil bucket
• Spring correction pads included to reduce factory spring bow
• Coilovers provide an additional level of adjustability to fine-tune ride, handling, and off-road performance

Geometry & Handling Corrections:

• Front and rear track bar geometry correction brackets to precisely center axles for on-road handling
• Adjustable control arms allow precision tuning of caster and pinion angle front and rear

Rock Krawler's Adventure-X2 coilover lift system is designed to be the most comprehensive long arm solution available for the 392 platform — equally capable of tackling rock trails and cruising the highway in comfort.
